Sir Michael Gambon said it would be "wrong" for Britain to vote to leave the EU.

The veteran actor is the latest star to lend his voice to the referendum debate, which has seen Sir Michael Caine also speak out in the past week.

Speaking at the premiere of his new film Dad's Army, Gambon said: "I hope we don't. I don't think we should leave the EU, it would be wrong. I don't think it's right."

He did not go into the reason behind his response, unlike Sir Michael Caine who backed an exit and said Europe was run by "thousands of faceless civil servants".

Asked which camp he would back in the in/out referendum, he said: "I don't know what to vote for. Both are scary. To me, you've now got in Europe a sort of government-by-proxy of everybody, who has now got carried away. Unless there is some extremely significant changes, we should get out."

Pressed by Radio 4's Today host Nick Robinson, he said: "I sort of feel certain we should come out."

Sir Michael Gambon's comments come on the same day as the ballot paper for the EU referendum was released.
